The Persian language is inflectional. The present study aimed to compare word-level inflections in the language samples of CI recipients and healthy-hearing children.<br> <strong>Methods</strong>: Thirty children were recruited in this descriptive-analytical cross-sectional study. The Language Sample Analysis (LSA) was used as a method of language production evaluation. Language samples were gathered using picture descriptions. A total of 3000 intelligible utterances were elicited and transcribed. An adaptation of the Language Assessment, Remediation, and Screening Procedure (LARSP) for Persian (P-LARSP), and the Mean Length of Utterance (MLU) techniques were used for the analyses of utterances.<br> <strong>Results</strong>: The stages of language development of CI recipients were lower than those of the healthy children. The obtained results indicated a significant difference between children with CI and healthy-hearing children in MLU (P=0.0001). Moreover, we found a significant difference between the study groups in the mean frequency of word-level inflections (P=0.0001).<br> <strong>Discussion</strong>: Children with CI use less word-level inflections, compared to their healthy-hearing counterparts.&nbsp;</span></span></p> <p style="margin: 0px; text-align: justify; line-height: 115%; unicode-bidi: embed; direction: ltr;"></p> Language Assessment, Remediation, and Screening Procedure for Persian (P-LARSP), Language sample, Cochlear implant, Persian, Word level inflections 387 394 http://irj.uswr.ac.ir/browse.php?a_code=A-10-523-4&slc_lang=en&sid=1 Safieh Samiee safsamiee@gmail.com 0000-0002-8154-1831 No Department of Speech and Language Pathology, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran.
